Dear Calvinus,
from my understanding the terrain modifier icons (the green mountains) are still wrong most of the time. When I look at the detailed combat reports, for example, they said only the defender gets a plus 1 for terrain. But the green icons show most of the time +2 defender -2 attacker. And they are not updated correctly, I think. From my reading of the boardgame rules, the terrain modifiers change with the number of combat rounds. Could you also check into this?
Thanks, Hanno
